Pre-stressed box girder bridge floor pre-buried creep intubation tube detection device

The utility model belongs to the field of prefabrication of prestressed box girders of high-speed railways, and particularly relates to a bridge floor pre-buried creep intubation detection device for a prestressed box girder. Comprising a pre-embedded insertion pipe reserved in a box girder bridge floor, the pipe bottom of the pre-embedded insertion pipe falls on the mold bottom of a box girder, and the pipe top is flush with the girder surface; the device further comprises a sleeve which can be guided into the pre-embedded insertion pipe, the sleeve is in clearance fit with the pre-embedded insertion pipe, a plurality of positioning holes are formed in the wall of the sleeve in the axial direction, bolts penetrate through the positioning holes, a detector platform is arranged on the sleeve, and the bolts penetrate through the corresponding positioning holes to support the detector platform at the preset height. A detachable waterproof cap is arranged at a pipe opening of the embedded insertion pipe. The pre-
